Perfect Chroma Catalyst is a Tint in Clair Obscur: Expedition 33 that upgrades a weapon to level 33. Guides report several ways to obtain one, including boss rewards, a quest, and the final challenge in the Endless Tower; their lists differ, so check the routes against your own progress rather than relying on a single guide as a complete inventory.

What does Perfect Chroma Catalyst do?

The item description reproduced by the community wiki says it can be used at camp to upgrade weapons to level 33. It is a Tint used for that upgrade, not a general-purpose currency.

How to use it

  1. At camp, interact with the Curator and choose Upgrade Weapons, as described in Game8’s weapon upgrade and item guide.
  2. Select the weapon you want to upgrade and use the catalyst for the level-33 upgrade. Other upgrade levels may require resources that vary by weapon and level; Gamer Guides’ item entry notes that resource costs vary.

Gamer Guides says Curator access follows clearing Flying Waters. Game8 also says Expedition Flags can be used for weapon upgrades starting in Act III.

Where to find Perfect Chroma Catalyst

Walkthroughs report different sets of rewards and locations. These are routes they name, not a confirmed exhaustive list for every version or playthrough:

Route What the guide reports
Endless Tower Game8 lists the reward for clearing Stage 11, Trial 3, which requires defeating the Painted Love combination. The community wiki also lists the final Painted Love challenge.
Serpenphare The community wiki lists a catalyst from Serpenphare in The Continent. Gamer Guides identifies Serpenphare’s reward as Battle Loot.
Lampmaster Listed as a boss route by Game8 and Gamer Guides.
Évêque / Eveque Gamer Guides lists Évêque; Game8 lists the Flame, Frost, and Thunder Eveques.
Clea Listed by both Game8 and Gamer Guides.
Chromatic Création Listed by the community wiki and Gamer Guides; the wiki places it in Renoir’s Drafts.
Trash-can Man The community wiki lists a reward from Trash-can Man in Lumière during Act III.
Fading Boy The community wiki lists a catalyst for fulfilling the Fading Boy’s request in the Painting Workshop.
Other map entries Gamer Guides describes six map locations and names Serpenphare, Lampmaster, Évêque, Clea, the Stage 11 Trial 3 reward, and Chromatic Création; it does not detail the sixth entry in the summary.

Because the guide lists are not identical, compare these names with your save’s completed bosses, quests, and challenges. The community wiki entry is explicitly marked as a stub, so its list should not be treated as definitive.

Is it a missable reward?

The cited guides do not establish a universal missable status or guarantee that every listed reward remains available in every playthrough. If you are checking for one you may have missed, use your in-game progress to identify which named boss, quest, or Tower trial is still incomplete instead of assuming a fixed total.
